GCC modified for the FreeChainXenon project

CFG cleanup computes dominators before the loop over blocks looking for merging opportunities. That computes also the fast-query DFS numbers but that's a bit pointless since any CFG cleanup will invalidate them immediately (they are re-computed before fixing up loops). The following avoids this and fixes the SIGSEGV due to the deep recursion in assign_dfs_numbers after inlining very many small functions. PR tree-optimization/108500 * dominance.h (calculate_dominance_info): Add parameter to indicate fast-query compute, defaulted to true. * dominance.cc (calculate_dominance_info): Honor fast-query compute parameter. * tree-cfgcleanup.cc (cleanup_tree_cfg_noloop): Do not compute the dominator fast-query DFS numbers. |

This directory contains the GNU Compiler Collection (GCC). The GNU Compiler Collection is free software. See the files whose names start with COPYING for copying permission. The manuals, and some of the runtime libraries, are under different terms; see the individual source files for details. The directory INSTALL contains copies of the installation information as HTML and plain text. The source of this information is gcc/doc/install.texi. The installation information includes details of what is included in the GCC sources and what files GCC installs. See the file gcc/doc/gcc.texi (together with other files that it includes) for usage and porting information. An online readable version of the manual is in the files gcc/doc/gcc.info*. See http://gcc.gnu.org/bugs/ for how to report bugs usefully. Copyright years on GCC source files may be listed using range notation, e.g., 1987-2012, indicating that every year in the range, inclusive, is a copyrightable year that could otherwise be listed individually.
